Definition

The Safe Drinking Water Act (SDWA) is a federal law enacted in 1974 aimed at ensuring the quality of Americans' drinking water by setting standards for water contaminants. It establishes regulations for public water systems to protect human health and the environment by regulating the levels of various pollutants and ensuring safe drinking water access.
